Abstract: We report the discovery of a new spin glass ground state in the transitionmetal monosilicides with the B20 crystallographic structure. Magnetic,transport, neutron and muon investigation of the solid solutionMn$ {1-x}$Co$ {x}$Si have revealed a new dome in the phase diagram withevidence of antiferromagnetic interactions. For Mn rich compounds, a sharpdecrease of the Curie temperature is observed upon Co doping and neutronelastic scattering shows that helimagnetic order of MnSi persists up to$x=0.05$ with a shortening of the helix period. For higher Co $0.05
